WILLIAM dummen PHILADELPHIA, rENNsrnv/inn\ I IMPROVEMENT IN vELocIPI-:Dss

Specification forming part lof-Lctters Patent No. 117,220, dated April 11, `1865.`

' and I do hereby declare th at the following isa full, clear, and exact description thereof, refen' ence being had tothe drawings annexed and making .part of this specification, and the letters of reference marked thereon. Q

The nature of my invention consists in making a velocipede with levers operatedby the .hands,`and also with treadles operated by the feet, and in so arranging and constructing the VDarts that they, can be easily adjusted and altered at small expense to snit the 4individual who may require to use it without rendering the apparatus expensive in rst cost, and at the same time ai'ording an increased durability to the wearin g parts by reason of improved construction of some of the minor details of the apparatus. 1

Figure 1 represents a plan of `the velociped e. Fig. 2 represents a rear elevation of the velocipede. Fig. 3 exhibits a side elevation of the velocipede. Fig. 4 exhibits a front elevation of the velocipede. The remaining figures exhibit parts in detail. Fig. 5 exhibits a driving or hind -Wheel and axle. Fig. 6 exhibits a hand-lever. Fig. 7 exhibits the front axle. Fig. 8 exhibits one of the connecting links or -rods for transmitting motion from the treadle" to the crank. Fi g. 9exhibits aconnecting-link I for coupling the two cranked axles together.

Fig. 10 exhibits one of the connecting `links or rods for transmitting motion from the handlevers to thecrank. I Fig. 11 exhibits the fulcrum-bearing of the treadles. Fig. V12 exhibits the box or bottom of thefulcrumbearing, and Fig. 13 exhibits the top or cap of the same. Fig. 14 exhibits the" upper portion of one of thetreadles. VFig. 15 exhibits the backview of-one of the crankaxle bearings, and Fig. 16 exhibits the side view of the same.

A is the seat B and B', brac( s supporting the seat from the back axle-bearing, G.'

D is a brace orv perch supporting the seat VA from the braces or perches E E'. I

F and F are the hind or driving wheels on the cranked axles G and G. H and H are the front or guiding wheels,

one of winch, Hit-"is fastened upon the axle I and rotates with` it, and the other, l1', is 'se- 4cured upon the axlel by means of apio, K, ttingon the groove L, thus leaving H{ free to rotate independently of the axle I. I

M'and M are 'stirrup or treadle levers suspended by the tuleruinbearing N, and operated by the feetiof occupant ofthe vehicle. V

The pendulous motionof I the treadle-lever M and M are converted into a rotative motion` in the axles Gand G' bymeans ofl the Icon-1 I necting rods or links O and` O' andi'cra'nks P and P in a manner obvious'to-every machinist;`

Q and Q are-handlevers Iwhich are formed with two arms, the upper'ones, B and R", being lfor the handsof the operator `to propel'thex machine with, and the lower ones, S and SQ being connected with the cranks P and 1?'` by y means of the connecting rods or links. T and; I

T impart a rotative motion to the cranks PJ audi, and thus propel the'vehicleff ""llielinl.'` I Z holds the cranks P and `P diametrically opposite to each-other `without rigidly holding them in the same axial line.; I I

Thefconstruction of the lfulcrum-bearing of` I the stirru ps is peculiar. `.[t consists of a bottom piece, U, shown in Fig 12anda cap, V, showin` lin Fig. 13, which, whenplaced together, -present an end view, asjshown in Fig..1I.` The I upper ends ofthe sttrrnps or treadle-levers are I1 cylindric, and have grooves WV in them, asI y shown in Fig. 14, 'which grooves iift in a collar, X andl XJ, in the bearing, as shown in Fig. 12. I

The combined etiect ofthe collar Xx and groove I W is to retain'the stirrup-lever in thebearingp and at the same time to permit 'the levert/of V swing backward and forward `with the' motion of the feet of the operator. The cranked axles arehel'd in their proper places by meansofl the bearing-boxeeY and Y. I, (Shown in Figs.

15and 16 indetail.) The fulcrunr-bearing of` the treadles is easily adjusted by unscrewing"L it from the perch D and screwing it on again either higher or lower, to adapt it tothe size of theoccupant of the vehicle.

locipedes in generaLnse. l f I I I ,Y I am aware that velocipedes have been made TheV guidin g-wheelsare controlled and steery 1 ed in the same manner as in the ordinary veand operatedby the hands, and also that they have been made and operated by thefeet, andl l therefore do not claim either my invention p but What I do claim as my invention,y and dcsirc to secure as such by Letters Patent, is-

1. The combination of thc two cranked axles G and G', with thc connecting-.link Z, with the beaming` C, substantially for the purpose as described and shown. f

2. The construction of the fulcrum-bcaring N'of 'the trcadle-lcvers when used in Acombinascribed and shown.

3. The construction and hrmngcment cf thc frame as hereinbcfore set forth and described.
